Referencing `Microsoft.WindowsAppSDK.WinUI` causes conflicts with transitive dependencies?

[karmeye]

Describe the bug

When changing PacketReference from Microsoft.WindowsAppSDK to Microsoft.WindowsAppSDK.WinUI I get errors like:

Duplicate 'PRIResource' items were included. The .NET SDK includes 'PRIResource' items from your project directory by default. You can either remove these items from your project file, or set the 'EnableDefaultPriItems' property to 'false' if you want to explicitly include them in your project file

Duplicate 'Page' items were included. The .NET SDK includes 'Page' items from your project directory by default. You can either remove these items from your project file, or set the 'EnableDefaultPageItems' property to 'false' if you want to explicitly include them in your project file. For more information, see https://aka.ms/sdkimplicititems. The duplicate items were: 'Controls\DateTimePicker.xaml'; 'Controls\ItemsRepeaterPage.xaml'; ...

@michael-hawker is this because of microsoft/WindowsAppSDK#5811 (comment)?

If so, could we track it here? If it is not related you may close this issue. But according to this comment it seems to be

Looking at that issue, it looks like it is because packages that build on top of WinAppSDK haven't yet moved to just referencing the component packages. So, what happens is if you reference the WinUI component package and also the other library project like CommunityToolKit, its transitive dependency for instance on WinAppSDK 1.6 gets brought down too.
